DUMPlNG-WAGON.

SPECIFICATION forming part of Letters Patent No. 496,048, dated April 25, 1893.

Application filed December 12, 1892- Serial No. 454,810. (No model.)

' ing wagons, and relates to a construction thereof by which I attain improved results, and also produce a very strong, durable and light wagon. The Wagon is provided with a box or platform pivoted near its longitudinal center so that it may be tipped toward and discharged at the rear, and I contemplate using with such box or platform, especially in the transportation of pressed brick and like articles, removable trays or false floors adapted to hold the brick, and which can by tipping the wagon or platform, be slid from the wagon bodily and deposited upon the ground, without any disturbance or handling of the brick or other articles contained in the trays.

The nature of my improvement I have fully set forth in the accompanying drawings, in which Figure 1 is a side elevation of my improved wagon. Fig. 2 is a longitudinal vertical section. Fig. 3 is a transverse section on the line 33 of Fig. 1. Fig. 4 is a plan of the wagon with the box omitted, and Fig. 5 is a section of the axle of one of the rear wheels.

In the drawings A may represent an ordinary wagon box. In the practical working of the invention however the vertical portions of the box may be omitted, it only being essential that a properly constructed platform or floor be present. The wagon body is provided with a centrally located transverse shaft B extending across beneath the floor of the box and having bearings in the longitudinal parts of the frame as clearly indicated at Fig. The outer ends of this shaft are adapted to receive a wrench or crank b which may be used in rotating it. The shaft acts as a wind lass whereby to wind up the flexible supports by which the box or platform is sustained from the upright side frames 0, hereinafter described, and also as a pivot upon which the box or platform may be tipped when the load is to be discharged. The flexible supports are shown at D D and one end of each is secured to the shaft B, so that when said shaft is rotated they will be wound up thereon. From this attachment to the shaft B, the flexible supports pass up and over idler pulleys E supported upon the rods e, the ends whereof are secured to the branches of the frame C, thence down and under the idlers a on the shaft B, and thence up to the top of the springs F positioned upon the apices of the frames 0. The frames 0 are each in the shape of an inverted V, with their limbs supported at the front and rear Wheels respectively. I make the frames in this form in order that they may be well adapted to sustain the weight of the load, and also to give them the height requisite to permit the raising of the box or floor to a considerable distance, which may sometimes be desirable. The springs F are mounted upon the apices of the frames, and the flexible connections pass through them and are secured in the top platesfresting upon the springs, as plainly illustrated, and by this construction the entire load rides easily as though it were entirely supported upon springs, and the wagon becomes well adapted to the carrying of pressed brick or other articles liable to be injured by the jolting of the wagon.

It will be seen from what has been already described that the wagon body may be raised by winding up the flexible support on the shaft 13 to any height permitted by the elevation given to the side frames 0. This may be a matter of great convenience, as the elevating of the box permits the turning of the front wheels to a much greater extent than would be possible if the box were not elevated. The ability to raise the box is also important in that the angle which it assumes when the load is to be dumped may be made steep or less steep according to the necessities of the case, and the unloading be thus greatly facilitated.

At the front end I provide means whereby the box may be held in a horizontal position, consisting of a chain G and a Windlass shaft 9 adapted to receive a wrench or other operating device. And inasmuch as the box may sometimes be elevated so that the front end does not rest upon the bolster H, it is also essential to provide means for holding the rear end down, and this feature I have illustrated as consisting of achain iattached to the cross bar J connecting the extended ends 0 of the side frames 0. This cross bar acts to unite the two frames 0 so that they are rendered mutually supporting. But when the wagon is to be dumped it is necessary that the bar be moved out of the way, and hence I pivot it at j to one of the framesC and secure it to the other one in any appropriate way, as for instance by a pin 19.

The frames 0 are each made of two pieces of channel bars united together at the apex of the angle formed by them by the splice 'm, which is desirably made of angle iron, and

which supports the spring F. The upper flange of the pieces 0 may be cut away at the top so as not to interfere with the flexible support D. The splicing piece is desirably riveted to the pieces 0.

The front wheels in my wagon are supported upon a continuous axle, but the rear wheels are necessarily supported on short axles N in order to avoid interference with the dumping. One of these short axles is shown in section at Fig. 5. It is provided with a head adapted to enter and fit the channel of the frame 0 and to be secured to the frame by rivets n passing through the head and the web of the frame pieces as shown. The axle and its head are best and most cheaply formed in one piece by casting them in malleable metal. A broad bearing is by this construction afforded to the axle which will enable it to sustain great weights.

The method of carrying brick and other articles easily broken or marred in trays is illustrated at Fig. 2, where the Wagon box is shown as tipped and a tray loaded with brick is in the act of being discharged. The tray which I prefer to use corresponds to the inner dimension and shape of the wagon box or floor, and consists of a floor 0, an end 0 and sides P. This tray is filled with the brick or other articles to be carried either before or after it is placed in the wagon. When the point of destination is reached, the tray is discharged bodily with its load by tipping the wagon until the end 0 rests upon the ground, and then drawing the wagon out from under the forward end. This gradually lowers the front end so that the entire tray is deposited upon the ground without any severe jar, and all this may be done without any disturbance to the brick in the tray, and without any handling of them whatever. After being thus discharged the brick may be left in the tray untilthey are used. The outward sliding of the tray from the wagon may be facilitated by providing the tray with rollers, and one such is shown at s. This method of unloading will also save a large amount of time.

I claim l. The dumping wagon wherein are combined a tipping box or platform, a central transverse pivot, side frames from which said pivot is adj ustably supported, and rear wheels revolving on short axles secured to said side frames, substantially as specified.

2. The four-wheeled dumping wagon wherein are combined front Wheels secured to a continuous axle and adapted to turn under the box, and a vertically adjustable box adapted to be raised and give room to permit the turning of said front wheels, substantially as specified.

3. The dumping wagon wherein are combined a tipping box or platform, and flexible supports for said box, one end of each of the supports being sustained by a spring, substantially as specified.

4. The dumping wagon having side frames constructed of channel iron, and stub axles for the rear wheels secured in the channels of the frames, substantially as set forth.

5. The dumping wagon having side frames constructed of channel iron, and stub axles for the rear wheels cast from malleable metal with beads adapted to be secured in the channels of the frames, substantially as specified.

O. The combination with a pivoted box or platform adapted to tip rearwardly, of a tray or false floor for holding the articles carried, said tray being adapted to slide out as the box or platform is tipped, substantially as specified.

7. The combination in a dumping wagon, of a box or platform tipping rearwardly, and a supporting frame having a cross bar or brace at the rear end which is made removable to allow the tipping, substantially as specified.

8. In a dumping wagon a tipping box or platform, flexible supports for said box or platform and means for fastening the box or platform against tipping, substantially as specified.

m 9. A dumping Wagon, wherein are combined a vertically adjustable tipping box or platform, side frames supported by the wheels, and yielding supporting devices by which the box or platform is sustained from the frames, substantially as specified.
